The Sea & Sea MDX-PRO MKIII underwater housing for the Canon 1D
Mark III and 1Ds Mark III digital SLR is beautifully machined. It
appears to be machined from a solid block of aluminum, and has a nice,
smooth finish (flat, black, hard anodizing).

The housing has a leak detector installed, which is a nice feature.
However, the detector's battery is mounted dangerously low on the back
half of the body. I would have preferred it to be mounted a bit higher
so minor leaks don't have the potential to destroy it.
The camera's rear LCD was easy to see through the large plastic window in the back of the housing.
The housing has been cut for an automatic focus light bulkhead, but
there is no bulkhead in place. If you use this hole for an accessory
bulkhead for any reason (e.g. remote shutter switch), you should be
aware that large dome ports will cover the bulkhead and will not allow
a connector to be inserted. However, the smaller optical glass dome
port does allow access to the bulkhead opening.

The 1D Mark III and 1Ds Mark III is mounted on a low-profile camera
base plate. It is different than the dovetail plate used in past Sea
& Sea housings, and slides in easily on top of a grooved, fixed
plate inside the housing. A large thumbscrew holds the two plates
together, and is easy to tighten and loosen. The thumbscrew does come
off of the base plate, so it's probably a good idea to keep a spare
somewhere in your accessory kit.
Without a zoom gear attached, the camera and lens -- with mounting
plate attached -- dropped perfectly into the housing. With a zoom gear
attached to a lens, I had to wiggle the zoom knob a bit in order to get
the gears to mesh together, which then allowed the camera to drop into
proper position. It is still easy to do, but it can be difficult unless
you are aware of the issue.

Assembly of the new housing out of the box
was straightforward, with no adjustments necessary. The housing has two
sync cord bulkheads, one wired for use with the TTL converter, and one
wired for non-TTL use. We used Ikelite N5-to-Ike sync cords which are
designed for manual use; these worked well when attached to both
bulkheads. However, our Y-cable would screw in properly only in the TTL
bulkhead. In the other bulkhead, there was significant resistance,
causing us to stop screwing it in rather than risk damaging the plastic
sync cord end. We're not sure if the problem was with the sync cord or
the bulkhead, but it is something we still need to figure out.

the TTL converter. The one of the right is designed for normal use.
